this is information on a product in full production. february 2016 docid2145 rev 25 1/46 l78l positive voltage regulators datasheet - production data features ? output current up to 100 ma ? output voltages of 3.3; 5; 6; 8; 9; 10; 12; 15; 18; 24 v thermal overload protection ? short-circuit protection ? no external components are required ? available in either 4% (a) or 8% (c) selection description the l78l series of three-terminal positive regulators employ internal current limiting and thermal shutdown, making them essentially indestructible. if adequate heat-sink is provided, they can deliver up to 100 ma output current. they are intended as fixed voltage regulators in a wide range of applications including local or on- card regulation for elimination of noise and distribution problems associated with single-point regulation. in addition, they can be used with power pass elements to make high-current voltage regulators. the l78l series used as zener diode/resistor combination replacement, offers e improvement along with lower quiescent current and lower noise. 627 72 62 www.st.com
